This study evaluates the relationship of change of dendritic cells fractalkine and P-selectin in patients with acute myocardial infarction.
Dendritic cells (DCs) are the most potent antigen-presenting cells, with the unique ability to initiate a primary immune response to certain antigens by activation of "naive" T cells, and are actively related to the process of atherosclerosis. Two DC subsets, myeloid DCs (mDCs) and plasmacytoid DCs (pDCs), were identified in humans. In our previous study, the investigators found that change of dendritic cells and fractalkine in patients with acute myocardial infarction. At the same time, the level of P-selectin increased. In addition, the interaction of dendritic cells and P-selectin promotes the progress of atherosclerosis. In this study, the investigators want to see whether the balance between mDCs and pDCs is altered in patients with acute myocardial infarction. sP-selectin is one of the members of the family of proteins, mediate leukocyte adhesion and rolling in vascular endothelial, studies have shown that in patients with unstable angina and acute myocardial infarction in serum sP-selectin protein increased significantly, showed that sP-selectin associated with the activity of coronary heart disease, causing plaque instability.However, there is few relevant studies about the relationship of dendritic cells and P-selectin in patients with acute myocardial infarction. This study valuates the relationship of dendritic cells and P-selectin in patients with acute myocardial infarction

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| STEMI group | The study population consists of 30 patients with ST-elevated acute myocardial infarction (STEMI,n = 30) who are admitted within 24 hours after chest pain attacks. They will all undergo coronary angiography.The diagnosis is made according to American Heart Association (AHA, 2014 and 2015) guidelines. Patients who had obvious blood system diseases,severe liver dysfunction, severe renal insufficiency,severe heart failure (NYHA class 3 and 4), acute or chronic infectious diseases, disease of immune system, asthma, malignant tumor, other advanced disease are excluded. |

| Control group | 15 age and body mass index matched healthy subjects with neither coronary artery disease nor any of the components of the metabolic syndrome are enrolled as Control group. |

|---|---|---|---|---|
| measurement | Other | Blood is obtained into ethylene diamine tetraacetic acid（EDTA） tubes from all subjects via antecubital vein puncture to measure the number of dendritic cells(DCs) and the concentration of sP-selectin. The number of dendritic cells(DCs) and the concentration of sP-selectin are measured in all patients with STEMI at 0 and 5-7 days after admission. The number of dendritic cells(DCs) and the only once in control group after admission. |
| Measure | Description | Time Frame |
|---|---|---|
| The number of dendritic cells(DCs)(percentage of total white blood cells) and the concentration of sP-selectin(ng/ml) within 24 hours after chest pain attacks | The number of dendritic cells(DCs) in percentage of total white blood cells;the concentration of sP-selectin in ng/ml | 24 hours |
| Measure | Description | Time Frame |
|---|---|---|
